What is GSM in Cotton? Why It Matters When Buying T-Shirts

Introduction

If you've ever bought a T-shirt and felt unsure why some feel thicker or softer than others, the answer might be in a simple term — GSM. It’s an important factor that tells you about the quality and feel of the fabric. Let’s break it down in simple words.

What Does GSM Stand For?

GSM means Grams per Square Meter. It tells you the weight of the fabric. The higher the GSM, the thicker and heavier the fabric will feel.

Imagine you have two T-shirts:

• One with 160 GSM (lightweight, airy, perfect for summer)
• Another with 240 GSM (heavier, more premium feel, great for cooler weather)

GSM Ranges and What They Mean

• 130–160 GSM: Lightweight. Ideal for hot weather or layering.
• 180–200 GSM: Medium weight. Great balance of durability and comfort.
• 220+ GSM: Heavyweight. Feels luxurious and lasts longer.

Which GSM is Best for Indian Climate?

In India, where most regions are warm for most of the year, T-shirts with GSM between 160 and 200 work best. They're breathable yet not too thin.

Things to Consider While Choosing GSM

• Are you buying for summer or winter use?
• Do you prefer thick premium fabric or light casual wear?
• Will you wear it at home, outside, or for gym?
